    The clock will display 12:59 when it is electrified and two alarm clock will be set by default. The first alarm clock is set at 13:01 and the second alarm clock set at 13:02. Short press S2 (right button) = switch between hour-minute and minute-second Long press S1 (left button) = setting menu A = Set Hours (S2 = 1)(S1 = OK and next setting) B = Set Minutes (idem) C = Hourly scheme switch (on = visible between 8:00-20:00)(S2 = on/off)(S1 = OK and next setting) D = first alarm (S2 = on/off)(S1 = OK and next setting) E = hour first alarm (S2 = 1)(S1 = OK and next setting) F = minute first alarm G = second alarm H = hour second alarm I = minute second alarm Watch out for the orientation of the black capacitor and black resistor.

    If you have never built an electronics kit before, then this is a great way to start. Easy to solder (start with the lower profile items first eg resistors and build up). I didn't realise that the clock was microprocessor controlled until I received it. Also, the power requirements are quite low and you can easily power it off batteries or a USB port. Unfortunately I did not see any instructions about how to operate the clock once built. So far I have learnt that the right hand button pressed once displays minutes and seconds. Pressing the right hand button again will return to normal display. Holding down the right hand button during minutes and seconds display will set the seconds to 0 (wait for two beeps) and stop the clock. Pressing the right hand button once more will start the clock again which is handy if you want to get the time exactly right. The left hand button held down during normal display will change the clock into setup mode (wait for the two beeps) and then the right hand button will change the hours cycling from 0 to 23. (You can hold down the right hand button to speed up the changes but note that upon release the number will change one more time.) Press left hand button again to change minutes with the right hand button. Press left hand again for chimes (beeps on the hour) turned on or off by the right hand button. Next (press the left hand button) is Alarm 1. If on, pressing the left hand button will allow changing of the hour and minutes respectively (using the right hand button). If off, pressing the left hand button will skip to the next function. The next function is Alarm 2, utilised in the same way as Alarm 1. Pressing the left hand button one final time returns the clock to normal display. The alarm, when active, can be cancelled by the left hand button.

    No Instruction in English. No white dot on the resistor pack PR1 1K You can use this youtube Video for help : https://www.youtube.com/watch?v=DYEogmpORVw Or the INSTURCTABLES Web site : http://www.instructables.com/id/C51-4-Bit-Clock/step2/Soldering-the-smaller-parts/

    This kit doesn't need instructions. Its all printed on the board where everything goes. My Grandson and I put it together, and it works great. My Grandson well now take the electronic clock to his school for show and tell. Thank you Mr Banggood.

    I ordered this kit a little hesitant due to the note on the instructions not being in English. Ultimately, I think that helped because I had to go look up the parts, make sure I confirmed polarity where it applied, and in general make sure I knew what I was soldering and where. I would recommend soldering/welding the IC Socket first and then the display - it will make the board more stable for the remaining work.

    The package arrived in good condition, even though the delivery time was very high. One look that I do not like at this watch is the presence of 0 that appears on the display until 10:00. Otherwise it's OK. I've replaced the buttons with longer ones to fit into a box.
